Flare Loop Sizes in Young Suns

Schultz, J.; Nevalainen, J.; Väänänen, M. K.

We analyse 27 solar flares observed with GOES and RHESSI in the X-ray bands at 3.1--24.8 keV and 12--25 keV and in Hα . The flaring region diameter in X-rays is found to correlate with the Hα decay duration, and this correlation is used to approximate the flare loop semilength. We propose the method to measure the coronal loop semilengths in young…
